ELECTRIC HEATER.

To all whom it may concern: l

Be it known that I, PHrLrr F. APPEL, citizen of the United States,residin at Seattle, in the county of King and tate of lVashington, haveinvented s. certain new and useful Improvement in Electric HeatersMowhich the following is a specification.

invention relates to improvements in electric heaters of that classwhich areemployed for igniting cigars, and`the method of ignitingsaidvcigars, and the object of my invention is to provide an electric heaterwhich shall be of such form of construction as will provide passagewaysfor air therethrough whereby the end of a cigar to be lighted may 'bedisposed at the outlet end of said electric heater and the act oi draw-A ing air through the cigar will cause air to iiow through saidpassageways wherein the air will be heated to a high temperature, by aheating conductor disposed within said electric heater, which heated airwill quickly I accomplish this object by devices illustrated in theaccompanying drawings, whereinl Figure 1 is" a view of my invention infront elevation;

Fig. 2 is a view in longitudinal mid-section on broken line'2, 2 of Fig.l;

Fig. 3 is a view in cross-section on broken line 3, 3 of Fig. 2; and

Fig. 4 is ay viewin longitudinal mid-secl tion showing a modified formof details of parts, a hollow body portion my invention.

Referring to the drawings, throughout which like reference numeralsindicate like 5 of cylindrical form is made of retracto material that isa non-conductor of electrlcity, as porcelain or plaster of Paris, andembedded therein are two electrical conductors 6 and 7 which aredisposed to ext-end from circuit connectors '8 and 9 (with which theyare respectively connected) each to and through the back end wall 10 ofthe body portion 5.

The hollow heating element of cylindrical form, comprising the endportion 12, end portion 13, and the annular body portion 14, is made ofrefractory material that is a non-conductor of electricity, the innerspace 15 of said heating element being flared at its end portion 12 -toadapt it to guide the end o a cigar into the inner space 15.

Embedded within the circular walls of Applicationl led August 27',

the inner space 15, with a part of its surface exposed within the innerspace 15, is an electrical heating conductor 16 whose ends 17 and 18 areextended to and through the end portion 13.

Disposed to surround the heating element thereby forming a passagewayfor air from the exterior of said heating element throughthe holes 20,thence through thepassageway 22, formed by the tube 19 and the bodyportion 14, thence through the openings 21 into the recess 15.

The heating tube 19 may be element including the metal conductor 16 willmake contact with the circuit wires 6 and 7.

The construction of my invention as shown in Fig. 4 is similar to theconstruction shown 1n Figs. 1, 2 and 3r with ,the exception of the4winding 'of the heating conductor and the construction of the bodyportion of the heating element.

ln Fig. 4, the electrical heating conductor 23,' like the conductor 16of' Fig. 2, with part of its surface exposed within the inner space 24,is embedded within the lcircular walls of the inner spaces 24 and isextended to and embedded within the annular body portion 25' with a partof. its surface disposed snugly tol t within l the inner space 11 of theloody/portionv whereby the ends 17 and 18 of the heatingl -forming acircuitv extending from the outer surface of the heating element to andAwithin the inner space 24 thereby aording a larger exposed surface ofthe conductor' 23.

Disposed to extend through the 'body portions 25 are a plurality ofholes 27 which form a passageway between the passageway 26 and the innerspace 24.

The body portion'together with the electrical element may be inclosedwithin any suitable casing, not shown, whereby it may be adapted for useto ignite cigars.

The heating elements including the conduct'ors 16 and 23 may be made ofany of the different materials that .are well known to those skilled inthe art.

l The opera'tion of my invention as disclosed 'in Figs. l, 2 and 3 is asfollows: rIhre circuit connectors 8 and 9 are connected by welll knownmeans to a source of electrical current, not shown, thereby causing acurrent of electricity to iiow through the electrical heating conductor16 whereby the conductor 16 is heated to a high'temperature whereuponthe end of a cigar is inserted into the inner space 15 and by drawingupon said cigar air will be caused to flow from the exterior of theheating element through the' holes 20, thence through the passageway 22,thence through the openings 21 into the inner space 15 whereupon the`air is heated to a high temperature and is drawn directly upon the endof the inserted cigar causing it to be ignited.

'Ilhe operation of the device as disclosed in Fig. 4 is as follows: Thecircuit connectors are connected in a similar manner to the connectors 8and 9 of Fig. 2 causing the heating conductor 23 to be heated to a hightemperature whereupon the end of a cigar is inserted within the innerspace 24 vand by 'a drawing upon said cigar air will 'be caused to iowfrom theexterior of the heating element through the holes 20 thencethrough the passageway 26, where it is heated to a'high temperature,part of which heated air being drawn through the holes 27v and part ofwhich heated air being drawn through the openings 21, into haagse? theinner space 24 where it is again heated to a still higher'temperaturewithin the inner space 24, from which inner space 24 the heated air isdrawn directly upon the end of said cigar causing it to be ignited.

Obviously many changes may be made in' the forms, dimensions andarrangement of parts of my invention without departing from the spiritthereof.

What I claim is:

An electric heater of the class described, which embodies a bodyportion, and an electric heating element disposed within said bodyportion, said heating element being provided lwith a passageway for airadjacent one end portion thereof, another passageway for aircommunicating with the rst named passageway and -extending to the rearend portion of'said heating element and thence extending through thecentral portion of said heating element to the exterior thereof, saidheating element also being provided with passageways for air extendingfrom the second named' passageway to the passageway extending throughthe central portion of said heating element whereby air may be Iheatedduring its passage through all of said passageways.

In witness whereof, I hereunto subscribe my7name this 10th day of AugustA. D. 191

PHILIP F. APFEL.
